BURNER CONSTRUCTION. I 1

Application filed March 15, 1918. Serial No. 222,645. 1 I,

lowing tobe a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to makeand use the, same.

The invention relates. to a burner. construction, and .more particularlyto the class of steam generators and hydro-carbon burners for cookingstoves, ranges, furnaces or thelike..'- I

The primary object of the invention isthe provision of a burner of thischaracter, wherein water and kerosene are preheated to generate steamand gas, which commingle for producing an inflammable. fluid which whenignited possesses maximum heating quality and in this manner affording asaving in the consumption of kerosene and avoiding any waste thereof.

Another object of the invention is the provision of a burner structureof this character, wherein the parts thereof are readily accessible andthe arrangement thereof permits the ,easy mounting of the same within astove, range, furnace or the like, the structure being novel in form toassure the successful and perfect working thereof.

A further object of the invention is the provision of a burner structureof this character, which is comparatively simple in construction,thoroughly reliable and efficient in its operation, and inexpensive tomanufacture and install.

Other objects will be in part obvious and in art hereinafter pointedout.

he invention accordingly consists in the features of construction andarrangement of elements, which will be exemplified in the constructionhereinafter set forth, and the scope of the application of which will beindicated in the claim hereunto appended.

In the accompanying drawing Figurel is a fragmentary top plan view of astove showing the burner construction constructed in accordance with theinvention applied for,

Referring to the drawing in detail. A designates generally a portionvofa cooking stove, which in this instance is of the range type andhasformed therein as usual the fire box 5 the same being accessiblethrough the opening in the top of the stove andthis opening is closedthrough the mediuml of a lid or stove plate 6, which is removably fittedwithin the opening in the ordinary well lmown manner.

The steam generator and hydro-carbon burner, comprises a pair ofsubstantially shaped pipes 7 and 8 respectively which are disposedv invcross relation, to eachother and are adapted to depend within the firebox 5 in the stove A. The vertical limbs 10 and 11, respectively of eachpipe are passed up- Wardly through suitable holes in the lid or stoveplate 6 at opposite sides of the center thereof and these limbs aresecured or held fast to the plate in any suitable manner. Connected tothe limbs 10 of the U-shaped pipes 7 and 8 are branch pipes 12 whichhave leads 13 from a double chambered tank or reservoir 14 which issupported in any suitable manner at an elevated point on the stove orabove the same. The pipes 12 are fitted With suitably manually operatedcut-off valves 15 which control and shut off the flow of fluid in saidpipes. The reservoir 14 in its respective chambers are adapted tocontain kerosene and water of any desired quantity.

Mounted on the limbs 11 of the U-shaped pipes 7 and 8 are substantiallygoose neck shaped nozzles 16 the tips 17 of which are directeddownwardly toward the center of the lid or stove plate 6, which latteris formed with acentral opening 18 therein and these nozzles 16 deliverkerosene and water interiorly of the fire box '5 through the opening 18in the lid or stove plate 6.

Adapted to be contained within the fire box 5 to the desired heighttherein is a filling, preferably ashes, clay or the like 19Specification of Letters Patent. t t e 25,1913,
